B00F7 Third Row Right Inflatable Seat Belt Deployment Control

B00F7 closes the inflatable-belt block with the right seat of row three. No manufacturer documents it. The nearest real case is one row further forward: on the 2014–2016 Ford Explorer, the dealer bulletin for programme 21B11 names B141C as the right and B141B as the left second-row harness code and has technicians re-route or repair the seat pigtail when either appears. Ford's 2018 owner manual puts the rear inflatable belts in the shoulder webbing of the outboard second-row seats only; on the right of row three there are child-seat anchors but no bag. Mercedes lists beltbags for the outer rear belts of the S-Class, and Autoliv's 2002 patent shows one inflator feeding belts through a gas guide. With B00F7 present, the airbag lamp stays on.

Likely causes

Chafed wires in the right rear seat harness, as seen one row forward on the Explorer (B141C)
Restraint module variant coding expects a right third-row inflatable belt
Open or shorted igniter in the right third-row belt inflator

Symptoms

  • Airbag lamp stays on after start-up check
  • Right third-row inflatable belt not armed
  • Safety note: never probe the inflator circuit with a test lamp; disconnect battery, wait, leave it to a specialist
